d J a Z Mme/mm 650/665 fi E' y 14 2901) GEORGE HENRY WOOD, F OLDHAM, ENGLAND.

FASTENEB, FOB SPLIT STEEL LUIBBICATING AND OTHER RINGS.

a subject of the King of Great Britain and Ireland, and resident of Oldham, county of Lancashire, England, have invented a certain new and useful Improvement in Fasteners for Split Steel Lubricating and other Rings, of which the following is a specification.

My invention relates to fasteners for split steel lubricating and other rings for shafting, pulley-boxes and the like, and the object of my invention isto produce by means of the improved fastener a ring which is perfectly circular, close fitting and easy to open and close.

The invention is illustrated by the accompanying sheet of drawings, in which Figures 1 and 2 are respectively plan and elevation of a ring constructed in accordance with the invention, the ring being shown in its closed and locked position.

Fig. 3 is a fragmentary plan view, partly in section, drawn to an enlarged scale to shplw more clearly the locking of the free en s.

Fig. 4 is a similar view, but showing the free ends unlocked or open.

Fig. 5 is a front view of said Fig. 4:.

Like letters of reference indicate corresponding parts in the several figures.

In carrying out my invention, the free end a of the member I), which is hinged at c- Fig. 1- to the other member 03, is provided in its width with a backwardly extending slot e--Figs. 2, 4 and 5terminating in an inwardly sloping bevel f and with a pin 9 extending across said slot and at a sli ht distance from the bevel, said pin 9 ta ing in the jaws h in said free end a formed by theslot, while the abutting edge 11 of said free end a is cut radially from the center of the rm 'l he free end of the member (1 is provided with a tongue is of a length and width corresponding to the slot in the free end a of the member I). This tongue is is formed with a I Specification of Letters Patent.

i Application med February 16, 1917. Serial No. 149,106.

bevel m, and in the rear of said bevel m there is provided a semi-circular and transverse groove n, while the side extensions of the tongue is, that is to say, the abutting edge 0 or end of the member d, are cut radially from the center of the ring.

With this arrangement of device it is only necessary to bring the free ends a and d together and exert slight pressure thereon, the tongue 76 of the member d by its bevel m riding over the pin g in the slot 6 of the member a and then springin down, engaging by its transverse an semi-circular groove n said pin g-Fig. 3-and at the same time jamming the bevel portion m of the tongue is between the bevel portion of the slot 6 and the pin 9 thereof, thus making a perfectly circular ring.

Slight pull on the free ends of the hinged members causes the forward edge of the semicircular groove to ride up over the pin, instantly loosening the fastening.

Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is A lubricating ring consisting of two hinged members provided with fastening means at their free ends, said means comprising a backwardly extending slot in one of the members terminating in an inwardly slopingbevel, and a pin extending across said slot, a tongue on the other hinged memher having a beveled forward edge provided with a groove to receive said pin, said tongue being of a length and width corresponding .to said slot in the other member, and the abutting edges of the free ends of both of said members being cut radially from the center of the ring.

In testimony whereof I have afiixed my signature hereto this th day of January 1917.
